Shares in social gaming company Zynga, which Tech.li recently covered in an expose, are frozen after 13 percent declines. Heavy downside volume triggered Nasdaq’s so-called “circuit breakers,” which the exchange put in place after the Flash Crash of 2010.

$ZNGA collapsed when $FB opened. Off 13%. Maybe no one wants to own a $FB proxy now that they can own $FB??

Zynga’s social gaming business relies heavily on Facebook as a distribution network. Declines in Zynga shares could be a market reaction to Facebook’s initial 13% pop, or these declines could simply reflect investors’ decisions to dump a once-hot social tech stock in search of greener (or bluer) pastures.

As this is a developing story, we will update you when more news hits the wires.

Jason D. Rowley does not like being wrong. He is a writer, startup founder, sometimes landscaper and gardner, and his libraryâ€™s best customer. Jason is heavily involved with the entrepreneurship scene at the University of Chicago, where he studied political science before â€œtaking a breakâ€ (e.g. dropping out, noncommittally) to work with his classmates on his current project, which will debut shortly. Heâ€™s written voluminous, ripsnorting articles for Flyover Geeks (now Tech.li) for over six months and publishes on Tuesdays. Edward Domain and others have described him as â€œobstreperousâ€, a label he wears with not inconsiderable pride. Jason, in spite of these claims, is a pretty nice guy.
